I Application filed September 23, 1921'. Serial No. 502,746..

To all whom it may mm.-

Be it known that I, JoHNO. BUCHENAU,

, a citizen of the United States, and a resident form and the general object of my invention is to provide a device adapted to constltute. an adjustable tie and spacer between the tion of the Wall;

of De Witt, in the county of Onondaga and State of New York, have invented a new and Improved Adjustable Form Tie and Spacer, of which the following is a descriptlon.

The invention relates to a wall mold or sides of the form. A more specific object of the invention is to provide for adjustably connecting the sections without the employment of bolts, screws, or other adventitious fastening means, although the invention in all its phases is not limited for practical embodimentto a sectional tie self-contained as to the means for adjustably connecting the sections.

The above and other objects are attained by a novel device hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the draw ings are merely illustrative of one example of the invention; e

Figure 1 is a horizontal section showing a tie and spacer illustrating the same in connection with a wall form or Figure 2 is an enlarged perspective view of the tie and spacer;

Figure 3 is av plan .view of the tie and spacer slightly modified with respect to the means for adjustably connecting the sections.

In Figure 1 the numeral 10 indicates the planks or other material forming the sides of the Wall mold, and 11 indicates portions of uprights to which said sides are secured. My improved tie and spacer is formed of two similar sections 12 which advantageously are made of channel material. Each sec-.

tion is formed with a plurality of transverse openings 13 in the web thereof and the ter mi'nal 14 of each section is given a form to be passed through said openings and be disposed at an angle for interlocking the two sections. The separate holes 13 permit of the tie being adjusted to suit walls of different thicknesses. In the form shown in Figures 1 and 2 the inner terminals 14 are returned into hooked form. In the form shown in Figure 3 the inner terminal 14* of one mold and a see section 12 may bepassed through the transverse openings in the other section. The terminals instead of being return bent into hook form are bent forwardly at an angle, the

naterialat the base of the angular terminal having a transverse direction to take the tensile strain on the tie and hold the sections rial are widened as at 20 and accommodate the nut 18. If desired, in order to hold the nut 18 to the sections 12, the widened portions of the sides 20 may have indentations 21 therein.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim: I

1. In an adjustable tie and spacer for inner and outer sides of a wall mold, a channel member having a plurality of slots in the web, a tongue atone end and a socket'at the other for receiving a nut.

2. In an adjustable tie and spacer for mold boards, a member presenting a socket at one end adapted to receive a nut and slots adjacent its central portion adapted to engage the opposite end of a similar member cot-acting therewith. f

In an adjustable tie and spacer for wall molds, amember presenting at one end laterally extending flanges to accommodate a nut, and at the other a bendable tongue adapted to be inserted in transverse slots in the body of a cooperating similar member.

4. A tie and spacer for wall molds comprising a pair of oppositely disposed channel members having adjacent their central portion transverse slots, each of said members presenting at one end a bendable tongue adapted to engage said slots, and at the "opposite end a socket adapted to receive a nut.

5. In a tie and spacer for wall molds, a member presenting laterally extending 5 flanges, said flanges being Wider at oneend and turned laterally inward to form a reinforced socket adapted to receive a nut, and

at the other end terminating short of the end of the member Wherebya bendable tongue is 1 presented.

6. In a tie and spacer for Wall molds, a member presenting laterally extending flanges, said flanges being Wider at one end and turned laterally inward to forma reinforced socket adapted to receive a nut, and at the other end terminating short of the end of the member whereby a bendable tongue is presented; together with bolts for securing said member to a mold board.

JOHN C. BUCHENAU.
